PURPOSE: The purpose is to evaluate the feasibility and effect size estimate of a 1-month customized home training program (EPIC WheelS) for improving wheelchair mobility skills among novice older adult manual wheelchair users compared to usual care. Despite the pervasive use of wheelchairs as an intervention in rehabilitation, the evidence for training in effective wheelchair use is still underdeveloped. Structured training has demonstrated excellent potential, but the most effective and efficient means of providing that training remains unclear. Larger multi-site clinical trials are required to establish evidence to inform and direct clinical practice. The investigators propose that this 2-year feasibility trial is not only critical, but also prudent, prior to moving forward with an expensive large multi-site randomized controlled trial (RCT). Specifically the results of this study will address 1) feasibility outcomes (i.e., recruitment and retention; trainer and subject burden; safety; intervention administration and adherence; perceived benefit) and 2) clinical outcomes (i.e., effect size calculations for the primary and secondary measures). Although the principal intent is feasibility, the sample size calculation is based on the primary clinical outcome to provide a reasonable estimate of an effect size for planning the subsequent large scale RCT.
